How are clay tiles made?
Differing levels of manganese oxide in the sand give the different levels of colour desired. Once the sand has been added to the surface of the clay hand made roof tile, the tile is placed into the mould and is pressed and any excess clay is cut off with a wire.
How long do clay tiles last?
Clay or slate tiles may last more than 100 years, while most concrete tile comes with a 50-year warranty. Slate is one of the most durable and long-lasting roofing materials, with a lifespan of 100 to 150 years or more.
